ozone action plan
Ozone Action Plan
  • Meet monthly with the Ozone Action Group on the Coast and DeSoto County to discuss Ozone Reduction Measures.n
  • Identify leaders on the Coast and DeSoto County to initiate voluntary ozone reduction activities
  • Participate in outreach activities
pm 2 5
  • EPA is scheduled to propose revised PM2.5 NAAQS in January 2011.
  • The final standards will be issued in October 2011.
nitrogen dioxide
Nitrogen Dioxide
  • In January 2010, the NO2 NAAQS retained the current annual average of 53 ppb and added a 1-hour average of 100 ppb.
  • Roadside monitoring will be required in Jackson by January 2013.
  • Initial designations will be made by January 2012 and redesignate areas in 2016 based on the roadside monitoring data.
  • In October 2010, the final secondary standard will be issued.
nitrogen dioxide1
Nitrogen Dioxide
  • Pascagoula is currently the only NO2 monitoring site in Mississippi
  • 2009 Annual Average - .005 ppm
  • NO2 Annual Average Standard – 0.053 ppm
  • 2007-2009 1-Hour Average – 47 ppb
  • NO2 1-Hour Average Standard – 100 ppb
sulfur dioxide
Sulfur Dioxide
  • In June 2010, the final SO2 NAAQS replaced the current annual average and 24-hour average standards with a new 1-hour average standard of 75 ppb.
  • Designations will be issued by June 2012.
  • In October 2010, the final secondary standard will be issued.
sulfur dioxide1
Sulfur Dioxide
  • Pascagoula is currently the only SO2 monitoring site in Mississippi.
  • 2007-2009 1-Hour Average – 37 ppb
  • SO2 1-Hour Average Standard – 75 ppb
  • In 2008, the primary and secondary lead NAAQS were changed from 1.5 ug/m3 to 0.15 ug/m3.
  • Mississippi last monitored for lead in 1995.
  • The new regulations require lead to be monitored in the Jackson Metro Area starting January 1, 2011.
  • Designations will be issued by November 2011.
carbon monoxide
Carbon Monoxide
  • The proposed CO NAAQS primary standard is scheduled to be issued by October 28, 2010.
  • The final standard is proposed to be issued by May 13, 2011.
  • MDEQ does not currently monitor for CO.
access to ambient air quality data
Access to Ambient Air Quality Data
  • For MDEQ Annual Air Quality Data Summaries:

Go to www.deq.state.ms.us, click on Office of Pollution Control, go to Air Monitoring

  • For EPA Airnow data: http://www.airnow.gov
greenhouse gas reporting rule
Greenhouse Gas Reporting Rule
  • Electronic Greenhouse Gas Reporting Tool (e-GGRT) due out late summer 2010
  • Training on e-GGRT starting fall 2010
  • Deadlines for 2010 reporting year:
    • Certificate of Representation – January 31, 2010
    • Annual emissions Report – March 31, 2010
  • For more information http://www.epa.gov/ climatechange/emissions/ghgrulemaking.html
ghg tailoring rule final may 13 2010
GHG Tailoring RuleFinal : May 13, 2010
  • By January 2, 2011, Step 1 of the rule says that only sources currently subject to the PSD Program would be subject to GHG permitting if there are GHG increases of 75,000 tpy.
  • By July 1, 2011, Step 2 of the rule, builds on step 1 and will cover for all first time new construction projects that that emit more than 100,000 tpy of GHG or make modifications at existing facility that increases GHG vby 75,000 tpy.
  • MS Law provides the Commission with statutory authority to administer and regulate federal pollution control legislation and programs, including the TV and PS permitting programs. MS will be amending its PSD (APC-S-5) and TV (APC-S-6) by January 2, 2011.

ms deq lead based paint program
MS DEQ Lead- Based Paint Program
  • The lead program’s active involvement with the Mississippi State Department of Health’s (MSDH) Childhood Lead Poisoning Prevention Program (CLPPP) continues to be a major lead program activity. During 2007, CLPPP, along with the Mississippi Childhood Poisoning Prevention Lead Advisory Committee, developed a plan known as the Childhood Lead Elimination Plan. The lead program is an active member on the Lead Advisory Committee which was convened in 1998 by the State of Mississippi to address childhood lead poisoning. As a member of this committee the program assists in the efforts to eliminate childhood lead poisoning in Mississippi by assisting in the following:
  • Development and implementation of the Mississippi Childhood Lead Elimination Plan.
  • Providing lists of state accredited training upon request.
  • Assisting in community outreach initiatives on the hazards of lead-based paint.
  • Informing building and paint contractors of the lead-based paint regulations.
  • Assisting in health fairs to inform the public of the hazards of lead-based paint.
  • Assisting in workshops and conferences.
  • Mississippi Department of Environmental Quality (MDEQ) electronic Environmental Site Information System (enSite) which is a One Stop Integrated Information Management System. First it allows the certification system to be maintained in house. It also allows greater flexibility in providing data to the general public such as providing current lists of certified firms and individuals on line.
  • Provide lead-based paint outreach to all counties within state annually especially ones with children with elevated blood lead levels.
